The evolution of rice: molecular vignettes on its origins and spread

The domesticated species Oryza sativa or Asian rice evolved starting approximately 9,000 years ago and from its centers of origin in China and India has subsequently spread throughout the Old World (and in historical times in the New World as well). This species is one of the key domesticated crop plants in the world and has emerged as a model for studying the origins and spread of domesticated taxa as well as in investigating the genetic basis for plant variation under domestication. Archaeological data has been critical in dissecting the origins and spread of rice throughout Asia, but molecular information has also provided a complementary approach to examining the evolutionary dynamics of this species. The evolutionary history of a species can leave its footprints within its genome. Moreover, genetic studies allow us to study the history of traits that do not leave an archaeological record—for example, grain stickiness or flowering time—which can provide insights into how crop species are adopted by different cultures. In this review, several molecular studies into the origin and spread of Asian rice are discussed and we explore the advances these genetic studies offer in our understanding of the evolution of domesticated species. We also explore how archaeological data can provide critical insights that can help refine genetic models of the origin and spread of domesticated species.     

Ancient DNA typing of archaeological pig remains corroborates historical records

The recent increase in both the abundance and taxonomic range of DNA sequence data in public repositories makes it possible to determine the maternal origin of lineages of faunal archaeological material by characterizing its mitochondrial DNA. Among the most commonly represented taxa are domesticated animals, for which extensive genetic characterization has revealed high levels of genetic diversity and (in at least some cases) strong phylogeographic clustering. Such information has significant implications not only for characterizing important aspects of the occupation history of archaeological sites, but also in providing novel insights into colonisation history and the scale and scope of trade and exchange networks. This can be done through studying the origins and dispersal of proxy organisms such as commensal and domesticated animals, as well as economically important wild fauna. To illustrate this approach, we compare historical records of maritime movement of people and pigs from two sites on Lord Howe Island, Australia, to phylogeographic results of DNA extracted from pig bones.     

Phylogeography of einkorn landraces in the Mediterranean basin and Central Europe: population structure and cultivation history

Einkorn (Triticum monococcum L.) was one of the first cereals to be domesticated in the Old World ca. 10,000 years ago and to spread towards Europe and North Africa. Its cultivation declined before the Iron Age and it remains today only as a relic crop in remote areas. To investigate if the geographic distribution of genetic diversity in modern einkorn landrace accessions could be informative about the movement of this crop during prehistory, we genotyped 50 accessions of einkorn from Europe, North Africa and the Near East. Using nuclear and chloroplast microsatellites and clustering methods, we detected two main gene pools in einkorn. The distribution of these lineages revealed differences between accessions from Morocco and the Iberian Peninsula from the rest of Europe and the Near East and suggests different regional dynamics in the spread of this crop.     

Debating Some Past and Present Research Frameworks and Methodologies in History on Places and their Peoples in South Africa

ABSTRACT

Histories regarding places and their peoples in South Africa can be traced to the early days of History being practised as an academic discipline. However, practising this form of history under (and outside) the flag of regional history was formalised only in the mid seventies, while informalised research practices in the field continued as methods complementing various schools of thought. Narrowly perceived local histories were considered as inclusive of the formalised and informalised regional history practices as knowledge contributing towards a broader understanding of a (geographically defined/ politically demarcated) region. Of interest is not only the historiography in this field (of which a few pointers are shared in this discussion) but some of the frameworks and methods to research and to record regional histories that have been used in the past. Equally of interest are the ways in which these frameworks and methods are still applied and thought of as dynamic and progressive to assist the historian to progress towards producing and packaging research as part of a comprehensive, all inclusive approach in creating knowledge as regional history studies. In South Africa, an extensive debate on how regional history studies should be broadly defined and understood when undertaking research, still falls short. This is due to the variety, diversity and complexity of knowledge contributing to the pool of information that should be packaged as regional history studies. To contibute towards a framework of understanding and packaging knowledge in this field of meaning to regional history studies, the reader is further exposed to an extended structure of perhaps understanding and doing research in this field: a field that has always been regarded as having the potential to be both integrative and multidisciplinary by nature. Yet its integrative analytical abilities also rest on the outcome of narrow-defined histories done on spaces and places before it is possible to embark on bigger research analyses in, for example, the spirit of modern social history applications to regional history studies. This discussion on ways to understand the limited past and present of regional studies (historiographically and methodologically) in South Africa is offered to encourage further debate.     

Economic Diversity and Regional Socioeconomic Performance: An Empirical Analysis of the Western Australian Grain Belt

One of the truisms ingrained in much regional development policy and practice is the claimed importance of economic diversity in contributing to socio-economic stability and well-being. There is, however, very little recent research examining this contention in the context of rural Australia. This paper examines the extent to which economic diversity affects the socio-economic performance of local areas in the Western Australian grain belt. The results indicate that employment diversity across industry sectors is clearly associated with population growth, labour force expansion, labour force participation, and rising median incomes. However, the paper also argues that economic diversity is not necessarily the cause of these changes, but simply one, albeit important, component of the dynamics of regional change.     

Chickpea domestication in the Neolithic Levant through the nutritional perspective

An alternative approach to the process of selection and domestication of grain crops in early history based on nutritional value is proposed. Selection by a long trial and error process among a number of wild large seeded legumes gave rise to a nutritionally superior domesticated chickpea among the selected “founder crops” of the Neolithic Near Eastern agriculture. We found considerably higher free tryptophan levels in cultivated stocks (44 desi and 29 kabuli types from 25 countries; 1.10 mg/g seed dry weight), compared with the wild progenitor Cicer reticulatum (15 accessions; 0.33 mg/g seed dry weight). Dietary tryptophan determines brain serotonin synthesis, which in turn affects certain brain functions and human behaviour. We suggest that these nutritive facts may explain the decision of prehistoric farmers to choose this rare species and struggle to keep such an agronomically complicated crop under domestication.     

HISTORY,MIGRATION AND CHILDHOOD: BASQUE REFUGEE CHILDREN IN 1930s BRITAIN

Abstract

The arrival, in May I937, of 4000 Basque refugee children in Britain serves as an important reminder that the history of childhood consists of diverse identities and experiences.At least where refugees are concerned, the extent and nature of this diversity has been crucially shaped by state policies on the principle of asylum. The specific policy of favouring the arrival of unaccompanied children in inter-war Britain illuminates contemporary constructions of the nature of the child. In addition, the policies put in place to receive and settle the children crucially shaped their experiences in exile. Yet these policies were implemented in regional settings and more detailed local studies are required if this marginalized but important aspect of childhood history is to be understood.     

多元的时间和空间视阈下的19世纪中国社会——几个区域社会史的例子

Should studies of social history engage in questions of important socio-political changes? The answer is undoubtedly affirmative. So far as the important changes in 19^th century China are concerned, some case studies in regional social history have presented a picture of greater complexity and diversity. The Ningbo case, for example, shows that when a port that has had a history of foreign trade becomes embroiled in conflict between Chinese and foreigners, this conflict may simply become one mode of interaction amongst many between Chinese and foreigners. The case of Turmot is an important turning point in Chinese history, since it marks the reversal of 2 000 years of frequent attempts by nomadic tribes to expand southward. This trend is completely reversed by the Han nationalities’ northward immigration and reclamation, a development as significant as the Western invasion of China in terms of consequent social transformations. These historical traces revealed from within regions deepen our comprehension of these social transformations; consequently, such studies in social history may manage to provide answers different from those offered by the traditional model of political history.     

Spatial dimensions increase the effect of cultural drift

The transition from hunter-gathering to agriculture (Neolithic) spread gradually across Europe from the Southeast. A reduction in cultural diversity of crop farming practices has been previously observed by comparing pre-LBK Neolithic sites in Greece and the Balkans (dated about 8500 yr BP) to LBK Neolithic sites in Central Europe (dated about 7000 yr BP). The decrease in crop diversity is statistically significant even when considering only the species less likely to have been subject to smaller productivity due to climatic factors (reductions in growing season, temperature, daylight, etc.). This reduction in cultural diversity has not been explained previously. In this paper we show that spatial drift, which occurred on the front of the advancing wave of pioneer settlements, can explain the observed loss of diversity during the LBK range expansion. Our results suggest that spatial dimensions can have a relevant effect also in other case studies in which cultural drift is important.

The origins of agriculture in North-West Africa: macro-botanical remains from Epipalaeolithic and Early Neolithic levels of Ifri Oudadane (Morocco)

This research aims to shed light on the early stages of agricultural development in Northern Africa through the analysis of the rich macro-botanical assemblages obtained from Ifri Oudadane, an Epipalaeolithic–Early Neolithic site from North-East Morocco. Results indicate the presence of domesticated plants, cereals (Hordeum vulgare, Triticum monococcum/dicoccum, Triticum durum and Triticum aestivum/durum) and pulses (Lens culinaris and Pisum sativum) in the Early Neolithic. One lentil has been dated to 7611 ± 37 cal BP representing the oldest direct date of a domesticated plant seed in Morocco and, by extension, in North Africa. Similarities in both radiocarbon dates and crop assemblages from Early Neolithic sites in Northern Morocco and the Iberian Peninsula suggest a simultaneous East to West maritime spread of agriculture along the shores of the Western Mediterranean. Wild plants were abundantly collected in both the Epipalaeolithic and the Early Neolithic periods pointing to the important role of these resources during the two periods. In addition to fruits and seeds that could have been consumed by both humans and domesticated animals, fragments of esparto grass (Stipa tenacissima) rhizomes have been identified. This is a western Mediterranean native plant that may have been used as a source of fibres for basketry.     

Ancient DNA confirms a local origin of domesticated chenopod in eastern North America

Domesticated chenopod was an important starchy seed crop in eastern North America before the rise of maize agriculture. Domesticated chenopod first appeared in North America during the fourth millennium B.P., however its wild progenitor and site of domestication remain unresolved. Archaeological evidence suggests a local domestication in the Eastern Woodlands, while morphological similarities with modern Mexican cultivars indicate a possible introduction from Mesoamerica. To distinguish between these two scenarios, we isolate chloroplast DNA (cpDNA) from modern and archaeological North American chenopods sampled from across their geographic range. Our results demonstrate that the chenopod grown in the Eastern Woodlands was locally-derived, indicating that independent domestication events gave rise to the ancient eastern North American and modern Mexican cultivars. These results strengthen the argument for an entirely native pre-maize crop complex with chenopod as a major component.     

Shell Middens, Ships and Seeds: Exploring Coastal Subsistence, Maritime Trade and the Dispersal of Domesticates in and Around the Ancient Arabian Peninsula

The Arabian Peninsula occupies a critical position at the intersect of several major Old World landmasses. Inland aridity and a major coastal perimeter have long made maritime activities critical to Arabia’s cultural trajectory. A wealth of recent studies, not previously synthesised, suggest not only that the peninsular littoral offered a rich resource base for thousands of years of human occupation in the region, but also that Arabia witnessed some of the world’s earliest seafaring and maritime exchange activities, and played a role in Bronze Age maritime trade that has often been underestimated. Maritime activities were closely linked to developments in agriculture, which not only fuelled trade and exchange, but were also impacted on by the dispersal of domesticates along early maritime corridors. While regional specialisation has to some degree prevented consideration of the maritime prehistory of the peninsula as a whole, it is clear that there are interesting parallels, as well as important differences, between cultural trajectories in different parts of the peninsula.     

International prototypes and local identity: The walled garden of Scotland as heritage landscape

Abstract

The distinctiveness of place is a central, and often unquestioned, tenet of landscape heritage studies and the landscape design and conservation which may accompany them. In learning from history and other comparative studies, one of the many challenges is to discern what determines diversity in the landscape. At what point does the local expression of an international prototype become a local and unique landscape type, a local landscape heritage, in its own right? This paper takes the walled garden of Scotland as an example to explore issues of national, regional and local landscape identities. It examines cultural traditions, biophysical constraints and stylistic responses to availability and command of materials and technologies. It explores some of the origins of the walled garden, the way the landscape type was developed and refined in response to the Scottish context, and the way this element is treated as landscape heritage today.

Local Histories,Global Markets: Cocoa and Class in Upland Sulawesi

Research and policy concerning the Southeast Asian uplands have generally focused on issues of cultural diversity, conservation and community resource management. This article argues for a reorientation of analysis to highlight the increasingly uneven access to land, labour and capital stemming from processes of agrarian differentiation in upland settings. It draws upon contrasting case studies from two areas of Central Sulawesi to explore the processes through which differentiation occurs, and the role of local histories of agriculture and settlement in shaping farmers’ responses to new market opportunities. Smallholders have enthusiastically abandoned their diversified farming systems to invest their land and labour in a new global crop, cocoa, thereby stimulating a set of changes in resource access and social relations that they did not anticipate. The concept of agency drawn from a culturally oriented political economy guides the analysis of struggles over livelihoods, land entitlements, and the reconfiguration of community, as well as the grounds on which new collective visions emerge.     

Identification of maize in absorbed organic residues: a cautionary tale

Starchy grains are an essential part of human diet in most agricultural groups, and are attributed an important role in the development of complex societies. Maize is a starchy grain domesticated in Mesoamerica that was an important foodstuff throughout the Americas before Contact, and around the world afterwards. An experimental study of the degradation of maize lipids suggests that the unsaturated fatty acids comprising the majority of maize lipids degrade rapidly, producing a virtually unidentifiable organic residue after 3 months deposition. Compounds in maize lipids decompose variably, depending upon depositional environment, making calibration of organic residue degradation impracticable. Variable decomposition of components of absorbed organic residues makes a wider range of improved experimental studies important, and suggests that identifying maize, and by implication starchy grains, from chemical analysis of absorbed organic residues requires a wider range of approaches than those previously attempted.     

Prosperity,power, and change: Modeling maize at Postclassic Xaltocan,Mexico

Documenting the relationship between agriculture and political economy occupies the center of much research and debate in anthropological archaeology. This study examines this issue by focusing on maize at Xaltocan, a Postclassic community located in the northern Basin of Mexico. We consider how different mechanisms of distribution, circulation, and production can influence maize variation. We analyze maize variability through time at Xaltocan and the community’s chinampa system and interpret patterns of variation in relation to its historical trajectory. This methodological and interpretive approach offers an innovative means to understand how agricultural practices transformed in relation to changing conditions of prosperity and power, especially the links between tribute, market exchange, conflict, and regional demography. Our study also speaks to broader, dichotomous perspectives that model the organization of agricultural systems, revealing that the strategies of both agriculturalists and the state often converge at local levels.     

Regional Innovation Systems and Economic Performance: Between Regions and Nations

This article aims at assessing the diversity of regional innovation systems and their economic performance in Europe. We propose to adapt the social systems of innovation and production (SSIP) framework at the regional level by identifying the specific arrangements of each part of the innovation and production system. Three key features of European regions are investigated using this framework: the diversity of regional SSIP, the interplay of regional and national determinants of such systems, and the impact of SSIP on regional performance. We identify a typology of regional configurations resulting from the combination of scientific, technological, educational and industrial indicators, using multivariate data analysis. A variance analysis approach is then developed in order to test the existence of specific regional growth regimes. The results highlight a persistently high level of diversity of regional configurations, notably among knowledge intensive regions, but also show that national institutional settings remain of fundamental importance in shaping a number of regional configurations. A final conclusion relates to the weak correlation observed between the structural characteristics of regions and their performance over the 2003–2007 period: regional performance remains primarily shaped by national trends. Overall, the paper questions the regional dimension of these “systems”.     

Engaging with risk (or not): shared responsibility for biosecurity surveillance and the role of community gardens

Governance of risks to native flora and fauna and agriculture from disease and pests increasingly emphasises the importance of a ‘shared responsibility’ for biosecurity. Few studies, however, have examined factors that influence stakeholders' engagement with such risks and responsibilities, particularly in community, rather than agricultural, settings. In this paper, we focus on a group of stakeholders in a context of heightened regional biosecurity activity, in northern Queensland, Australia. We explore the role that community garden actors may or may not play in biosecurity surveillance. Through interviews with 16 community garden group leaders and local government representatives, we unpack external social factors that contributed to stakeholders' engagement, unengagement, or disengagement with and from biosecurity risks. These factors included institutional characteristics such as land tenure and the presence or absence of management policies and guidelines. However, we found that less formal institutional characteristics such as social networks played a greater role in shaping stakeholder engagement. Unengaged stakeholders were typically unaware of risks posed by plant pests and diseases and had limited network connections to relevant government agencies but expressed an interest in learning and participating in biosecurity surveillance networks. Disengaged stakeholders were more knowledgeable of biosecurity risks and had established network connections but expressed a low interest in or willingness to report a potential biosecurity threat. This case study provides insights into important social dimensions of governing risk among stakeholders and offers recommendations to improve stakeholder engagement within biosecurity surveillance networks.
